20080274932 | COMPOSITION FOR IN SITU MANUFACTURE OF INSOLUBLE HYDROXIDE WHEN CLEANING HARD SURFACES AND FOR USE IN AUTOMATIC WAREWASHING MACHINES AND METHODS FOR MANUFACTURING AND USING - A composition useful in hard surface treatment and particularly useful in automatic warewashing is provided according to the invention. The composition may comprise a pretreatment composition, a detersive composition, a rinse agent composition or a combination thereof. The composition includes water-soluble cation and a source of alkalinity. The anionic alkaline source is selected from at least one of hydroxide anion or carbonate anion or a combination thereof. The cation is selected from magnesium, titanium, and aluminum, or combinations thereof. The source of alkalinity is provided in an amount effective to provide a use composition having a pH of greater than about 7. The cation is present in sufficient amount to form an in situ conversion agent. A conversion agent is a water-insoluble hydroxide precipitate that causes calcium in hard water to precipitate as aragonite thereby softening the water. The insoluble hydroxide reduces the contact angle of water on hard surfaces such as wares thus reducing water spotting. Methods for using and manufacturing such compositions are provided. | 11-06-2008 |
